My invention further comprises the cletails of construction and arrangement of parts which are hereinafter more partimr larly described in their preferred emhodi ment only, reference being had to the accompanying drawings, in which Figure 1 illustrates top plan view of the typewriter and calculator assembled for joint operation and broken away in parts to illustrate the operating n'ieohanism in plan View.

' 1:? Hill the 3- at their 1U oils 7 at their C(Hlldlill below the with to engage a uh project from connected to the bottom of the casing 10, there being preferably one such plate for each rocker shaft 9 As seen in Fig. 2, the front transverse rows of keys of the calculator machine which bear the numeral 1 will operate the front shaft 9, the row of keys d signated 2 will operate the second shaft d so on throughout the series, all calculator keys the same denomination of numeral figures being adapted to operate the mine shaft 9, Couplings 13 are slidably mounted on the squared ends of shafts 5. i mount similar couplings on the left hand ends of the shafts "1) which are likewise :ilillili'fiti. These several couplings are pro aided with a circumferential groove to re ceive cmipling shift ba rs, there being a common shift bar 1-2 for the front couplings on the shafts and a shift bar 15 for the rear couplings on the shafts 5, and a shift bar 15 for the muplings on the shafts 9. The several shift bars are alike in construction and are formed. by an angle plate which is notched at intervals so that it will have a slip fit in the grooves in the couplings after the fashion of a yoke to permit the couplings to turn freely. Each of the shift liars 1e and 15 have their ends bent at right angles and connected by screws to connecting bars 17, oneof which bars is connected to an intermediate point of the shift controller lever 18 which. is pivoted in a hear-- ing 19 at the bottom of the casing and. projects through a top opening in the casing preferably attlic right hand side thereof. As the lever 18 is moved toward the rear, both shift bars 1% and are moved rearwardly with it. This will cause the forward couplings 13 to become disengaged from the squared ends of the alining shafts 1: which transmit movement, when coupled to the key operated shafts, to the mechanizm (not shown) for operating the for ward accumulating or total dials 20 which carry numerals that are exposed through suitable top openings at the front end of the calculator casin The same movement of the lever 18 throws the rear couplings l3 into engagement with the squared ends of shafts 21, which operate the mechanism (not shown) for moving the rear or calculating dials This operating mechanism for the inis may be of any suitable type such as that shown in my Letters Patent No. 842,682, or in my application of even date herewith. The coiph gs 13 have squared openings which enable theinto readily act to connect the several key controlled rock shafts 5 with either of their respective alining shafts 19 or 21, according to the position of the lever 1.8. The left hand connecting bar 17 (Fig. carries a. pairof rank pins 23 mountc on plates 24 lio x 5 or iiveted to tl'ie bar, and each pin is adapted to engage in a slot in the bifurcated end of a horizontally 2, the plates A l are above "'i' movable crank arm :oi'inccted to a ert': cally disposed. pivoted. me nher i eh mounted in suitable bearin at a side of the casing auov end a horizontally mo. pivotally coniiected to a hill. turn is connected by a pine to the shift bar 16 for tl on the shafts t. in nu 1 disposed allow the angle 24 which support the pins 15- and have the pins ween-i l'zlllf fll'l'llfint in he i. l iwaiiahlc spa: in the (BUfiIlliCilHQ rod ii is (Fig. l) the pins :32 SW15 means of the linlrs Li 3 wi l draw bar 18 to the left and more the imup aiiyr 13 on the transierse we their squared outer ends ends of a series of r, shafts 30 carried by the merit, and couple each or spective alining shaft 1 The typewriter frame 333 .rcsh. on its iii, ion feet 33 and has connected to it a i 31, bent up at each side and -viii};- i A inturned flanges and with la: the flanges 3% and 35 ceive between them i! a side bar 36 of the tygmvwii in an; to be locked in engagement o KWl tll by a clip 3? which hooks over the top lm- H 36 and connected ii; i W to the flange Also set screws in the flanges 3i serve to make the rrmuection of. the iittachment more rigid to the typewriter frame. The plate is thus suspended from the type writer frame as an attachment which does not in any manner interfere with the ordinary use of the machine and leaves it free to be moved'about at will. the shafts 30 at one end are journaled in the upturned end il-ii wall of the frame 31 and are supported at their inner ends in bearings 40 formed by angle plates attached to plate 31. As there are nine of these shafts 30, there will be nir i of these bearing plates -10, and to make Ll a frame 31 more rigid i bend it to prov uh. longitudinal rib 41 between the bearing sup ports for each shaft 30. Along the rear cri of plate 31 I mount a series of nine standards 42 formed by vertical plates which 13 0 carry at their upper ends studs 43 on each of which a bell crank lever 44: is pivotally mounted. The plates are disposed so that said levers will stand und the ins digit keys 45 of the typewrih:v As my preferred means of COXll'ifiilllljf each lever 44 to a key 45, I slip a bent metal clip M; over each digit key if! and connect the lower ends of the clip by a pin to a link 48 with an e ongated slo 4%? n which engages a pin 50 6n the upper end of the adjacent hell crank lever. The lower ends of these levers are each connected by a ro l M with a crank arm rigidly attucluid to one oi the shafts 3U. Each shalt 3!), which operates a given numeral key. is adapted to be connected up with a shaft U which is movable by the several calculator keys having the corresponding designating numeral. The slots 42* leave the typewriter numeral keys fre" or direct manipulation, and yet, through .he connections described, the typewriter numeral key ll be depressed by the manipulation of the corresponding calculator keys, when the typewriter and adding machine are connected for joint manipulation. As I prefer to inclose all the calculating mechanism within the casing 10, I provide openings in its side wall for the shafts 30, which openings effectively aline said shafts with shafts 9. The calculator is provided with any suitable type of mechanism, controlled by keys 55, to clear the dials 22 and respectively. The keys 56 are to prevent the carrying pr0cess from dial to dial. To insure the ready and proper connection of the twpewriter and adding machine, after the shafts have been passed through suitably spaced openings in casing 10, I provide lugs on theTasing 10 which may be long, as lugs 54 in Fig. 1, or shorter, as lugs 53 in Fig.2. Each lug 53 or is adapted to overlap the end of the flange and be fastened thereto by a pin or screw which may be readily removed to unlock the machines.

To illustrate the operation of my invention, as a complete billing machine. we will assume that the hill head has been inserted inth e typewriter, properly addressed, and the first item to be written out'is, say, 1H yds.-120 yds.-129 yds.:3$)3j; yds. 0 .0 :353146. The numbers 1-14,}, 120 and 120 are struck upon the typewriter keys and the lever 18 is drawn forward to couple the calculator mechanism with. the front dials and disconnect it from the rear dials and the typewriter attachment. The total of the yardage is then added up on the front dials 30 of the adding machine and the total is struck by the typewriter keys. Then this total yardage is multiplied on the same front dials and when the product is obtained, the lever 18 is pushed to the rear so thatthe adding mechanism is uncoupled from dials 2 and coupled to the rear adding dials and to the typewriter attachment, and the result is struck on the adding machine keys, which operation prints the total figures in the hill and at the same time places the total amount upon the rear :uzcumulatm dials 22. By this method the calculations are sure to be correct, and at the end of a bill the grand total is shown upon the rear accumulator dials and is then struck by the typewriter keys the bill. Thus the total of the hill when finished, can be checked with the total snow n upon the rear accumulators.
